![**Title: Magnesium Reaction in an Oxidizing Environment - Educational Overview**
### If Earth has an oxidizing environment, what would you expect to happen to \( \text{Mg}_{(s)} \) if left to sit over time?
**Image:**
- **Description:** The image depicts magnesium reacting with oxygen.
**Observation:** The magnesium strips in the image appear corroded and discolored, indicating a chemical reaction has occurred.
**Question Options:**
- **A:** Nothing would be expected to change.
- **B:** \( \text{MgH}_2 \) would form.
- **C:** \( \text{MgO} \) would form.
- **D:** \( \text{MgO}_2 \) would form.
### Explanation:
In an oxidizing environment, magnesium (Mg) would react with oxygen (O2) in the environment. As a result, magnesium oxide (MgO) is formed. Hence, the correct answer is:
- **C:** \( \text{MgO} \) would form.
### Conceptual Overview:
Magnesium is a reactive metal that readily combines with oxygen in an oxidizing environment to form magnesium oxide (MgO). This reaction can be summarized by the chemical equation:
\[ 2\text{Mg}_{(s)} + \text{O}_2 \rightarrow 2\text{MgO}_{(s)} \]
**Note:** The other options (A, B, and D) are incorrect for the following reasons:
- **A** is incorrect because a noticeable change is expected.
- **B** is incorrect because \( \text{MgH}_2 \) (magnesium hydride) formation requires hydrogen, not oxygen.
- **D** is incorrect because \( \text{MgO}_2 \) (magnesium peroxide) is less common and typically formed under different conditions.
